Small diameter seamless steel pipe, it can be called a small-diameter high-pressure boiler tube, small diameter high-pressure boiler tubes can also be divided into: small diameter seamless high-pressure boiler tubes and straight stitch (also called welding) small-diameter seamless steel pipe general steel tube diameter less than 89mm, 4mm above; can be collectively referred to as small-diameter high-pressure boiler tubes. Small diameter cold drawn seamless steel pipe is a hollow section, no seams around the round, square, rectangular steel. Seamless steel ingot is made of perforated or solid through the capillary tube, and then by the hot-rolled, cold-rolled or cold call is made. Production of seamless steel pipe plant with a hollow cross-section, a large number of channels for transporting fluids, such as pipes, pipe and solid steel bar, compared to the same torsional strength in bending, lighter, is an economic cross-section steel seamless steel, widely used in the manufacture of structural parts and mechanical parts, such as drill pipe, automotive drive shafts, bicycle frames and construction using steel scaffolding.
